PolySwitch Radial Leaded PTC Resettable PPTC 250V 0.12A For Telecom
Protection
Description Of The PTC Resettable PPTC 250V 0.12A
The TRF series is designed to protect against short duration
high voltage fault currents (power cross or power induction surge)
typically found in telecom applications (250Vrms). The series can
be used to help telecom networking equipment meet the protection
requirements specified in ITU K.20 and K.21.
Features Of The PTC Resettable PPTC 250V 0.12A
◆ Fast time-to-trip
◆ Binned and sorted narrow resistance ranges available
◆ 0.08 — 0.18 Hold current range, 60VDC operating voltage
◆ 250VAC interrupt rating
◆ Radial Leaded Devices
◆ Cured, flame retardant epoxy polymer insulating material meets UL
94V-0 requirements
